How to Care for Solar Panels After Installation for Full Output

A solar system needs little care. What homeowners can do themselves is observe and notify the service team. Any work that involves going on the roof or touching electrical equipment should be left to technicians.

For your safety, do not climb onto the roof or hose down the panels yourself while the system is operating.

What homeowners can do themselves

• Check power generation in the app regularly: compare the units generated each month. If output drops unusually, notify the service team.
• Look out for dust and dirt on the panels: thick dust, leaves or bird droppings reduce output. Notify the team to clean the panels; do not go on the roof yourself.
• Check the status lights on the inverter: note any message or code on the display, then take a photo and send it to the service team on LINE.
• Do not switch the system’s electrical equipment on or off yourself: if you are unsure, always call the service team for advice first.
• Notify us before extending or repairing your roof so the team can remove and reinstall the panels correctly.

Work best left to technicians

• Cleaning panels with methods and equipment that do not damage the panel surface
• Checking panel mounting points and the condition of the roof around the panels
• Checking cables, connectors and protective devices in the electrical cabinet
• Checking inverter operation and updating it according to the manufacturer’s recommendations

How often should panels be cleaned?

It depends on your home’s surroundings. Homes near roads, construction sites or large trees may collect dust faster. Use the generation figures in the app as your guide: if output drops even when it is sunny, it may be time to clean the panels or check the system.
